Physostegia 'Summer Snow' is a deciduous, bushy, upright perennial with silver-grey variegated foliage. It bears upright spikes of tubular white flowers. The plants can become invasive so best to divide them every other year.


Planting Season 1

From Early Winter TO Mid Winter

Plant in full sun or partial shade in early to mid-winter in a moist but well drained soil.

 

Planting Season 2

From Late Spring TO Late Spring

Plant in full sun or partial shade in late spring, in a moist but well drained soil.

 

Propagation by Seed

From Mid Spring TO Mid Spring

Fill a seed tray with seed compost, water and allow to drain. Sprinkle seeds over the surface allowing roughly 25mm space between seeds and cover with a thin layer of compost. Put tray in a clear polythene bag and place on a windowsill. When seedlings show remove plastic bag. When the second pair of leaves appear on the seedlings thin out to 50 mm spacing by removing the weakest looking plants. After 2 or 3 weeks and when danger of frost has passed plants can then be planted outside into required position.

 

Propagation by Division

From Early Autumn TO Mid Autumn

Using a fork dig up plant in autumn, try to keep the root ball as complete as possible. Split the root ball at the centre with a sharp knife or a spade. Replant the plants to the same depth as the original and keep well watered until established.
