You will receive Penstemon 'Twizzle Blue' as a healthy, well-rooted seedling, which you can plant directly in its permanent location. This plant loves direct and hot sun, so choose the sunniest, warmest, and most sheltered spot in your garden for it. Proper soil is absolutely essential for successful cultivation. It must be light, permeable, ideally sandy or loamy, and slightly nutrient-rich. If you have heavy clay soil in your garden, be sure to lighten it with sand and fine gravel before planting. Plant the seedlings at a spacing of about 35 centimeters, which corresponds to seven to nine plants per square meter. This spacing ensures good air circulation and promotes healthy growth.
During the season, the care for Penstemon is very undemanding, so even a complete beginner can handle it easily. The plant tolerates drier conditions well, so choose moderate watering and water only when the top layer of soil has dried out. Overwatering is strictly detrimental to it. During the summer, it does not require complex fertilization; standard soil quality is sufficient. From June to September, it will reward you with a flood of blue-violet flowers on upright stems up to 80 centimeters tall, which require no support. To keep the plant producing new flowers and blooming as long as possible, regularly remove the spent stems. This will support its overall vitality. A huge advantage is that this species does not suffer from any diseases or pests, so you can do without any chemicals.
Although it is a short-lived perennial that usually lasts three to five years in the bed, it can withstand frosts down to minus eighteen degrees. Wintering, however, is highly dependent on soil moisture. In permeable soil where water does not sit during the winter, it will survive the cold months without problems. Conversely, in wet conditions, its roots could rot. You can also grow Penstemon with great success in larger containers and planters on sunny terraces. Here, it is necessary to place a thick drainage layer of expanded clay or gravel at the bottom of the pot and use substrate lightened with sand. Before winter, move the container to a sheltered spot by the house or wrap it in insulating material so the root ball does not freeze.
