Where is the best place to plant penstemons?
Where do penstemons grow best? Penstemons thrive in areas with full to partial sun and well-draining soil. Take semi-ripe cuttings 5-10cm (2-4in) long in trays and pots of cutting compost in summer or early autumn. This is the easiest way to propagate penstemons. If you take cuttings in early summer, they could be flowering by the end of the season.Penstemons grow in most soils that drain freely, flowering prolifically in fertile soils. They need full sun.

Are penstemons a perennial?
Penstemons are reliable summer-flowering perennials in all but the coldest regions. Penstemons benefit from being deadheaded, which helps promote new flower growth and keeps the plant flowering for longer. Simply remove whole flower spikes as the blooms fade and new ones will grow from the base.Plants grown from seed may not bloom in the first season. A quicker method to acquire flowering penstemon is to buy nursery plants. In spring, plant them shallowly in the garden, spacing them 12 inches apart and ensuring the top of the root crown is slightly above the soil line.Penstemons typically flower in spring and early summer, though a few varieties and particularly hybrids can re-bloom again in late summer, and a handful bloom more or less continually. Penstemons are generally perennials, but the life span of different species varies widely and is affected by growing conditions.Spring is the best time to transplant penstemon. Wait for the last frost to pass, find a suitable location, then plant the seedlings in the ground. Although mature penstemon plants don’t require lots of water, keep newly planted penstemon moist the first couple of weeks after planting.
Do penstemons multiply?
Penstemons more than three years old grow into clumps with young plants growing along the outer edges. These can be dug away and replanted to a new spot in early spring. Most penstemons also can be propagated by rooting non-blooming stem cuttings taken in summer. Penstemons can become woody and leggy if they are not pruned hard annually. It’s quite straightforward to do: In autumn, cut back plants by about a third, leaving enough foliage to provide winter protection.Take semi-ripe cuttings 5-10cm (2-4in) long in trays and pots of cutting compost in summer or early autumn. This is the easiest way to propagate penstemons.Penstemons are perfect for growing in the middle of a mixed border. They do best in a fertile, reasonably moist, free-draining soil. A position in full sun or light shade is ideal.The answer is a resounding yes! You can root penstemon cuttings in water, and it’s a simple and easy way to produce new, healthy plants.

It is usually a much surer and quicker way to have more of those very desirable plants.Take penstemon cuttings from late summer to early autumn. Select soft growth without a flower. Take each cutting back to below a leaf joint and remove the lower leaves. More than one cutting can be put into a pot of cutting compost as long as the leaves don’t touch.Plant in a sheltered position with well-drained soil, out of cold winds.
