Description

16-20" tall x 15" wide. This new, super cold hardy beardtongue is a real breakthrough, offering gardeners the huge flowers previously seen only with tender Zone 7 or 8 English-style hybrids. Blooming in mid-summer on compact plants, 'Rubycunda's large white-throated, bright red flowers are the favorite of hummingbirds and bumblebees. This is a great beardtongue for more civilized garden conditions. Compost enriched garden loam.

Planting & Care

Tips for growing Penstemon (Beardtongue)

Penstemon are generally evergreen and have beautiful flowers that are very attractive to hummingbirds. Most varieties are rabbit resistant.

  1. They need “elbow room,” maximum sun, heat and don’t like to be crowded by other plants.
  2. Plant only in well-drained soils; clay soils and Penstemon are incompatible.
  3. Avoid overly enriched soils; too much compost and fertilizer will shorten their lifespan.
  4. They establish quickly and the amount and frequency of watering needs to be reduced after about 8 to 10 weeks to create dry conditions.
  5. When using drip irrigation, be sure to put the emitter off to the side of the plant, not right on top of the root ball to avoid overwatering the plant.
  6. Plant high, leaving the top of the rootball just above the surrounding soil to avoid burying the crown of the plant.
  7. Mulch with gravel or pine needles in arid climates. No mulch is needed where conditions are moister. Always avoid bark, grass clippings, or compost as mulch materials.
  8. Allow some of the plants to set seed (don't deadhead all of the flower spikes)*.
  9. Fertilize sparingly. One time each year in the fall is enough. Apply a light application of an organic or natural fertilizer such as Yum Yum Mix as a top dressing around the plants. Don't use high nitrogen water soluble fertilizer like Miracle Grow.

*To keep penstemon that have finely textured or matted evergreen foliage looking their best, you'll want to 'deadhead" them. Shear off the fading flowering spikes just as the plant is going out of flower. Gently bunch the flower spikes together with one hand and cut them off at the point where they go down into the mat of foliage with your clipper in your other hand. Recommended for the following varieties: P. pinifolius types (‘Compactum', ‘Mersea Yellow', ‘Nearly Red', ‘Magdalena Sunshine' and ‘Tall Orange Mix'), as well as Penstemon linarioides v. coloradensis and Penstemon virens ('Blue Lips').

"Arrived fine and all are growing well"

— Greenman99 (5/5)

Hummers love them!

"While the flowers aren't quite as big as the HCG pics yet Im sure they will get there and even though smaller the hummingbirds already love them. They also are a very brilliant red that stands out in the garden. I have 3 of these amidst a bunch of other flowers and grasses and they really pop!"

— Enthusiastic A. (5/5)

Not chipmunk resistant

"After being partially eaten by a chipmunk, I surrounded it with chicken wire. It came back and is doing great! Very pretty red flowers."

— Lisa (5/5)

I will probably buy this again

"I'm using it along a walkway down to my studio, near some other flowering plants"
