Pinus contorta 'Spaan's Dwarf' / Spaan's Dwarf shore pine
Pinus contorta var. contorta 'Spaan's Dwarf' is a dwarf, mostly globose selection of shore pine with thick, irregular branching and very short, dark-green needles, but will occasionally produce full-length needles at random. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and 3 feet (1 m) wide, an annual growth rate of 3 to 5 inches (7.5 - 12.5 cm).
[ Stanley & Sons Nursery ] A dwarf form of Coast Pine. Needles are green and only 1/2 inch long. Buds are dark and very long. Plant grows in the form of a natural Bonsai.
[ Iseli Nursery ] Short, closely set, dark green needles and a sweeping, irregular habit give this dwarf shore pine an unusual look that suggests coral. Named for the nurseryman who found it in Washington state, 'Spaan's Dwarf' develops a sturdy, open, upright branch structure and dramatic character with age. Slow growth and a wider-than-tall form make it a natural for rock garden, bonsai and container culture.
This cultivar was found in the 1950s, in the wild, on the Pacific coast near Long Beach, Washington, USA, by Oregon Nurseryman, Jon Spaan.

I have found this specimen great for quick bonsai work in large pots. Oversized pots can be left out (NOT heeled-in) year-round in zones 5 & 6.
