Tilia cordata seeds - Small-leaved lime

The Small-leaved Lime (Tilia cordata) is a large deciduous tree commonly found in parks and large gardens, both in urban and rural settings. Its foliage turns beautiful golden hues in autumn, but it is best known for its nectar-rich and delightfully fragrant flowering. This hardy and resilient lime tree tolerates pruning and urban pollution well. Given its size, it is often planted as a standalone feature or in rows. Lime tree seeds require a cold period to break their dormancy.

The Small-leaved Lime (Tilia cordata) belongs to the Malvaceae family and grows naturally in Europe. This deciduous-leaved species, adapted to partial shade, can exceed 30 m in height and thrives at altitudes up to 1500 m. It is mainly found in moist, deep, and fertile soils with a pH ranging from acidic to neutral, or even slightly calcareous. In regions with hot, dry summers, it may be susceptible to red spider mite attacks. Aphids, though attracted to its foliage, do not hinder its growth. Its remarkable longevity can reach 500 years. This lime tree has slow growth initially, but gradually accelerates. At maturity, it measures an average of 20 m in height with a spread of 15 m, adopting a broad, rounded silhouette. Its trunk is often short and sturdy with large, arched structural branches, some of which become trailing over time. Its bark, initially smooth and greenish to reddish-brown on young shoots, later develops furrows and turns dark brown with age. Its small rounded leaves measuring 5 to 8 cm feature a glossy green surface and a downy, glaucous-green underside with russet highlights. The foliage turns golden yellow and falls relatively early in the season. The flowering, in June-July, consists of pendulous clusters of yellowish-white flowers with a strong fragrance, loved by bees. These flowers are followed by small, dry, greyish, globose, smooth fruits, each with a wing, called samaras, which aid wind dispersal. The seeds naturally fall to the ground in autumn. Their germination is often limited by a significant physiological dormancy that requires several weeks of cold to break.

The Small-leaved Lime makes a striking addition to any garden, its broad, trailing habit providing light, rustling shade. Its buzzing, bee-filled flowering is a delight in early summer. It looks magnificent near perennial beds of ferns and epimediums, which thrive under its canopy. At the woodland edge, coloured-wood dogwoods and the snowball viburnum Viburnum opulus 'Roseum', with its white flower balls, complement its silhouette without overwhelming it. It also fits well in a wilder landscape, at the edge of a clearing where ornamental grasses, such as miscanthus, capture the golden autumn light, echoing its luminous foliage. Planted in rows, it creates a majestic avenue, offering a soft, shaded perspective that invites leisurely strolls.
