Description
Buddleja knappii | Knapp’s Butterfly Bush
Knapp’s Butterfly Bush is a multi-stemmed bushy evergreen shrub native to South Africa.
From a distance, Buddleia knappii looks similar to Buddleja loricata. However, it is larger in scale, with willow-like foliage that’s more than two times as long and with round orange eyes on the flowers, rather than square orange eyes. The sweetly-scented creamy white flowers bloom in terminal clusters surprisingly late in the summer and persist for quite some time, attracting a variety of pollinators to the garden. The young have fine, silvery hairs over their textured, leathery surface and as they mature, they turn a darker green. The leaf reverses are startlingly white with woolly hairs. The evergreen foliage makes it useful in the garden year-round.
The seed capsule is small and covered with fine, creamy-grey hairs that form dense woolly heads, which eventually split open to release very fine seeds. Buddleja knappii grows on dry or moist hillsides, among rocks or sheltered places on slopes, mountains and sometimes on stream banks at fairly high altitudes.
If any pruning is to be done, it should occur shortly after flowering because flowers will bloom on last years wood.

ROOTING INSTRUCTIONS:
How to prepare cuttings to root via rooting cubes inside a humidity dome.
- Upon arrival, give cuttings a new fresh cut on the bottom of the stem. Then set in a cup of water for a minimum of 15 minutes.
- After soaking, gently cut or scrape small marks into the bottom portion of the plant stem (½ inch) with scissors or a razor blade.
- Dip the scarred end of the stem into rooting gel or rooting powder (gel is superior). This can be done without rooting gel, but results are not as good.
- Insert the plant stem into a rooting cube (Oasis cubes, grow plugs, soil-cubes, rock-wool cubes, etc) and place into a nursery tray with a humidity dome over the top. One cutting per cube. Custom individual humidity domes can be made using plastic cups and/or plastic cling wrap.
- After the first 3-5 days, the humidity dome should be opened up or set ajar to slowly allow more air in as the plants start to root. At this point, the cubes should be allowed to become mostly dry before adding any more water.
- Once 2-3 roots grow out of the bottom of the root-cube, the plant can be transplanted into soil.
- More detailed rooting instructions will accompany your order.
