This is quite normal and not a matter for any worry or concern, it is likely to be in perfect condition for the time of year. Particularly in autumn and winter many shrubs will lose their leaves and look rather bare, gaunt and stick-like and from August onwards many perennial plants may not even be showing above the soil.\n\n We want you to be happy with your purchase and all our Firetail are checked and inspected visually before packing. at .  .
