Huge, deep orange-red tubular flowers open from dark tinged calyxes and 8-12" long spikes in summer and fall, when grown as a perennial, to potentially year round under warm tropical conditions attracting hummingbirds for miles! Mole Poblano Mexican Chocolate Scarlet Sage, a selection of Salvia gesneriflora, is more compact and flowers much longer than its parent growing to about 6-7' high and wide. This giant growing Salvia, the species is reported to grow over 20' high, is a shade tolerant, herbaceous to shrub-like tender perennial Salvia that is adorned with fragrant, large heart-shaped, fuzzy, quilted foliage and is anecdotally root hardy into zone 8A. Its only real drawback is that it should be grown in a sheltered area protected from strong winds and heavy rains as the stems are subject to breakage. It can be pruned to help keep the plant shorter, stronger, and fuller. Provide Mole Poblano Salvia with a moist to average moist, well-drained, fertile soil for optimum vigor and continuous flowering.
*Although this Salvia is considered to be both full sun and light shade tolerant consider giving it cool sunlight with light shade during the heat of the day, particularly in areas with hot summer climates. Provide with a loose, breathable, insulative mulch to help alleviate moisture stress, particularly under full sun conditions, and to protect the crown in areas where it is grown as a die-back perennial like in zones 8-9.
Salvias are considered the #1 plant for Hummingbirds with their tubular flowers designed for pollination by these amazing flyers. If your Salvia or Sage starts to look unkempt in mid to late summer consider giving it a light shearing or remove the spent flowering spikes to help promote new growth and flower production. An application of fertilizer at this time may also be beneficial in spurring flower production.
Grows To: 6-7'H x 6-7'W
This is the average expected mature height by width in feet or inches. Feet are represented by a single quote and inches by a double quote. Parentheses are used to indicate that the plant can potentially reach that dimension, although the sizes outside of the parentheses tend to be more typical. Under poor growing conditions plants may be slightly to significantly smaller, whereas excellent growing conditions can produce larger more vigorous plants.
USDA Cold Hardiness Zones:
USDA Cold Hardiness Zones were established to give gardeners, horticulturists, farmers, nurseries, and landscape architects a universal way to describe where a plant will survive with regard to average winter lows for a region. And these are averages, here in zone 8B ('A' represents the colder half of a zone and 'B' represents the warmer half of the zone and they are separated by about 5oF) we have seen single digits but that is the exception but should be noted by the daring gardener. Each zone is separated by 10oF and the map was updated in 2012. Our zones do not always agree but we try to use our own experience as to what can be depended on to return or have known reputable gardens and or horticulturists to reliably grow that plant in zones that are usually colder but sometimes warmer than what other resources have available. For more on stretching your cold hardiness zones see the ""Growing on the Edge Growing Guide". If you do not know your zone you can find it by clicking on the "USDA Cold Hardiness Zones" link here or above.
Outdoor Light: Cool early morning sunlight, Part shade, Part sun, Filtered shade, Bright shade, *Full sun
Full Sun - 8 hours or more of direct sunlight; Partial Sun or Partial Shade - 4-6 hours of direct sunlight; AM Sun or Morning Sun or Cool Sunlight - cool sunlight but usually in the shade during the heat of the day; Light Shade - Bright indirect sunlight for much of the day; Filtered Shade - may receive some amount of direct moving sunlight like through trees but usually not for any extended period especially during the heat of the day; Shade - no or very little direct sunlight, especially not during the heat of the day.
Indoor Light: Direct sunlight to High indirect sunlight if overwintering indoors
Direct Sunlight - preferably 4 or more hours of direct sunlight through an unshaded south, east or west facing window; High Light - may tolerate no direct sunlight but will need very bright indirect light for 4 or more hours; High Indirect Light - bright indirect sunlight for much of the day; Medium Light - bright indirect light for 2-4 hours or more; Low Light - (few plants can do well under very low indoor light levels but some may tolerate it) no direct sunlight with little bright true sunlight filtering into the area; Cool Sunlight or Cool AM(morning) Sunlight - direct sunlight like in an east facing window but not during the heat of the day and will likely also tolerate cool sunlight late in the day, filtered sunlight may also be tolerated.
pH Range: Mildly Acidic, Neutral, Mildly Alkaline
Acidic or Strongly Acidic - pH less than 5.5; Mildly Acidic - pH 5.6-6.5; Neutral - pH 6.6-7.3; Mildly Alkaline - pH 7.4-8.4; Alkaline or Strongly Alkaline pH higher than 8.4. Acid loving plants that are grown under alkaline conditions often exhibit nutrient deficiencies since the roots are not able to draw some types of minerals from the soil. Gardenias, for instance, may need to be sprayed with chelated iron. Most plants that are native to alkaline soils can be grown in neutral to mildly acidic soils successfully, although the opposite generally is not true.
Soil & Moisture: Average moist to moist (never soggy wet), well-drained, rich fertile soils. Mulch in zones 8-9.
These are the basic soil types and moisture levels where this plant will survive, not necessarily thrive. Drought resistant plants will need to be well-established, usually 2-3 years at a minimum, in the garden or landscape before they are able to withstand lengthy periods (weeks or months) without supplemental water. Most plants will grow and flower and or fruit best where they have ample moisture and nutrients available during the growing season. With that said, many plants, like prairie natives, are quite adaptable to soil types and can thrive in heavy clay as easily as a loose sandy loam.
Do you know the many benefits of a proper organic mulch? Click here to learn more.
A breathable organic mulch is not only aesthetically pleasing (looks nice) but can:
- Help to improve soil organic matter as it breaks down.
- Provide shade for the soil to help reduce moisture loss and prevent weed seed germination.
- Provide soil microbes, mycorrhizae (beneficial fungi), earthworms,and even nematode predators the necessary organic matter and ecosystem to thrive while their actions aid in improving soil tilth and or friability (think of this as the ease with which roots are able to penetrate the soil).
- Provide insulation to protect the crowns of tender perennials and die-back perennials giving gardeners up to an extra half a zone of winter warmth allowing us to grow that which we normally could not.
- Provide soil temperature moderation preventing premature soil warming in winter and providing a cooler root zone in summer.
- So which mulch is our favorite? Our preferred mulch is Longleaf Pine Straw which has: a natural weed preventative for the first year after it is applied; it is sustainably harvested; and it provides protection from soil erosion and doesn't float away, and yet is still both insulative and breathable; while Longleaf Pine Straw appears to last the longest in the garden and landscape in our opinion as compared to Loblolly.
Flowering Period: Summer to fall to year round under warm tropical conditions.
These are the times of the year that you can expect this plant to be in flower. Most of the plants that we ship are already of flowering size and may even be in bud or flower when they are shipped but this cannot be guaranteed. The length of time a plant is able to flower is often based on its size. The more mature or better established a plant is the more resources it has to be able to expend on flowering and fruiting. Some perennials, trees, shrubs, and most vines will need about 3 years of establishment to be large enough to begin to meet their true flowering and or fruiting potential. That does not necessarily mean that they will not flower in the interim but they may not be able to flower for as long a time span. The better the growing conditions like having ample available nutrients and moisture generally equates to quicker establishment and longer flowering periods.
Fertilizing: Early to mid spring, once new growth commences, until about mid to late summer.
In general, plants will require the most nutrients when in active growth and less when dormant. For indoor plants and tropical plants grown in a warm greenhouse or atrium this may be year round. For winter growing perennials, like Louisiana Iris that go dormant in late summer, this may mean fertilizing in fall and winter. For spring and summer growing perennials, and practically all trees, shrubs, and perennial and woody vines in the garden we generally start fertilizing as early as 6 weeks prior to bud break (about Valentine's Day here in zone 8B in Louisiana) and they can be fertilized up to about 6 weeks prior to the earliest expected hard frost or freeze (about mid-August here in our gardens). This allows for tender new growth, and the entire plant really, to "harden off" prior to what could be potentially damaging temperatures and ultimately causing more harm than good.
One of the most common questions that we get is what fertilizer do you recommend? Obviously it will depend on the particular plant but a good quality, slow-release, non-burning fertilizer is what we prefer. Each time it rains or each time you water your plants are getting fed. Most of these fertilizers are either slowly dissolved or osmotically passed through the outer layer of a pellet. We use Scott's Osmocote© 14-14-14 and 18-6-12 on 99% of the plants that we grow, it is more expensive than some fertilizers but we can depend on the results. DO NOT use common garden fertilizers (like 8-8-8,12-12-12) on acid loving plants as it may contain lime as a filler and so can be deadly to plants like Blueberries, Azaleas, and Camellias.
Pruning: Deadheading is not required but can be done to keep your plants looking clean. Prune as needed to control shape and size as well as for a stronger plant.
Know your plants' needs prior to pruning and not all plants need to be pruned. Selection of plants that will grow to the appropriate size for the given space will help to reduce maintenance like annual pruning. LSU Agcenter uses the apt saying "Right Plant, Right Place".
- Woody trees, shrubs, and vines that flower on new growth or new wood are generally pruned in late winter to early spring prior to bud break.
- Woody trees, shrubs, and vines that flower on old wood (last year's growth) are generally pruned once the flowering season has passed and prior to bud set.
- Some woody shrubs (like Spirea, Blueberries, Old Garden Roses) may only need pruning about every third year and then may only need to have the oldest non-flowering stems, dead or damaged wood, and sometimes the small twiggy stems removed. These oldest 'spent canes' are typically removed near ground-level to about 6" high to make way for and to promote the emergence of younger new stems.
- True perennials are typically pruned once the flowering stems have died back after flowering and seed set. Normally we are only removing dead stems once they have turned brown as the plant may reabsorb some of the nutrients in the flowering stems. Dead stems can be removed all the way back to near the crown or back to living healthy stems.
- Tropical and subtropical plants that are grown as die-back perennials (like Lantana and the Confederate Roses in zone 8) are generally pruned once bud break has occurred in spring. The dead stems above the crown may provide some additional protection from the cold and that is why they are left over winter.
- Plants (think perennials, annuals, and biennials) that flower heavily and then begin to look a little ragged due the spent flowering stems may be lightly pruned during the growing season as this will clean them up and the removal of the spent flowering stems and seeds may promote repeat flowering.
- Some perennials, tropicals, and annuals may benefit from periodic 'deadheading'. Often the removal of spent flowers and developing seeds or fruit may promote the production of new flowers but it generally is not a required maintenance.
- ALWAYS use sharp bypass pruners. The anvil type pruners are great for florists who need to crush the stem for water absorption, they are not meant for general use in the garden. A clean cut heals faster and reduces the chance for disease and or die-back to occur. Sterilize your pruners periodically and sometimes even between plants if there is a chance for viruses and or other diseases to be spread between them.
When to Plant: Uppot, repot or plant out in spring, once all danger of freeze and frost have passed and soils have begun to warm significantly, until about midsummer.
Preferred planting seasons ranging in order of the most optimum to least optimum times for ease of establishment. Container grown plants, like what we ship, can be successfully transplanted anytime of year as long as proper care is provided. This gives container grown plants an edge on bareroot plants. With that said, there are easier and harder times to establish some plants mainly due to the additional moisture required by the plant during the main growing seasons like spring and summer. If you keep that in mind there is no reason that the great majority of plants can't be added to the garden anytime of year.
Deer Resistance: Rarely BotheredDeer resistance is relative to how hungry the deer (or other herbivores) are, what food is readily available in their natural habitat, and how tasty a particular plant is. Few plants are truly completely 100% resistant to being browsed by hungry deer and other herbivores. Please realize that this is just a guide based on our experience and research but some plants may never ever be bothered.
Native To / Origin: US Gardens - Huntington Botanic Gardens introduction, species is native to the Sierra Madre Oriental mountainous region, Mexico
If the plant is a true species and not a hybrid or cultivar this shows where it is normally found naturally. There may be some variation in species that are seed grown, which many of our 'species plants' often are, in order to help maintain genetic diversity. If the plant is a "cultivar" (CULTIvated VARiety) and if the data is available, it shows who developed, discovered it, hybridized it, and introduced it as well as the year it was introduced. With cultivars you will also typically see the cultivar name in quotes at the end of the botanical or scientific name. The great majority of cultivars are clonally propagated from division, cuttings, and tissue culture so that they remain true to type so have the same desirable traits as the parent such as growth habit, flower, fruit, or foliage form. With forms (form or forma), varieties (var.), and subforms (subf.) you will see these abbreviations usually between two lower case words at the end of the botanical name. They may be propagated via division or cuttings but can also be grown from seed depending on the plant and what is required to maintain them true to type. Plants that have PPAF(Plant Patent Applied For) or PP followed by a set of numbers, are illegal to propagate clonally for commercial purposes without the implicit permission of the patent holder. Some plants may have the trademark symbol (™) or copyright (©) in the name. These plants may not be clonally propagated and resold under that name without implicit permission from the copyright or trademark holder. Plants may be both patented and trademarked.
