P (incisa × campanulata) 'Okame'
Flowers carmine-pink; calyx and flower-stalks reddish. March. This beautiful hybrid was raised by Collingwood Ingram, P. campanulata
being the pollen-parent. Despite the tenderness of this species, ‘Okame’ is completely hardy and makes a bush or small tree of neat habit. Propagated by cuttings. Award of Garden Merit 1952.Later, Capt. Ingram made the cross (P. incisa
× P. campanulata
) × P. sargentii
. One of the resulting seedlings, named ‘Shosar’
, has flowers similar to those of P. sargentii
but produced some weeks earlier. It makes a narrow-crowned tree and colours well in the autumn.
