Botanical Name

CUCURBITA moschata 'Rumbo'

Plant Common Name

Rumbo Pumpkin

General Description

This appealing hybrid offers heavy yields of flattened, pumpkin-like squash with pronounced ribs, long curving stems, and unique, deep tan skin. Resembling old-fashioned wheels of cheese, the decorative fruits have tender, sweet, non-stringy, deep orange-yellow flesh which is excellent for pies, roasting or steaming. ‘Rumbo’ makes an unusual but fun Jack-o’-lantern, especially when other oddly shaped or colored winter squash are thrown in the mix! It is ready for harvest approximately 95 days from sowing.

Like many winter squash, ‘Rumbo’ is derived from the species Cucurbita moschata, a warm season, annual vine originating from the Americas. These large, rambling plants cling to supports via tendrils, and form roots along the stems as they spread. The enormous lobed green leaves have a coarse surface texture that can irritate the skin. As with most cucurbits, separate male and female flowers appear on the same plant. The male flowers appear first on the vine followed by the female flowers, which have distinctive bulbous ovaries at their bases. These blossoms are large, golden yellow and pollinated by bees.

Sow the seeds of winter squash directly into mounds of rich, light soil after the danger of frost has passed. Full sun is required for successful flowering and fruiting. To reduce the risk of fungal problems, avoid unnecessary wetting of vine stems and leaves. Monitor closely for stem borers, leaf bugs and beetles, and protect from browsing deer, birds and rodents in autumn. Cut squash from the vine before heavy frost when the rind is firm and solid in color, leaving enough stem for easy handling and to discourage fruit rot. Take care not to cut or bruise the skin, and store fruits in a cool, dry, frost-free location, leaving space between for good air circulation.
